Android Problem Overview

I can't compile my Android Kotlin project.

I have no idea what is this...

Gradle log:

error: supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath: class android.support.v7.app.AppCompatActivity, unresolved supertypes: SupportParentable

Android Solutions

Solution 1 - Android

In my case I had a library module with an abstract application class implementing Dagger's HasActivityInjector and an application module with a dependency to the library and its own (non-abstract) application class extending the base app class.

My Gradle dependencies were implementations, and therefore not accessible to the application module's application class (even though there were no imports there, otherwise the issue would be immediately obvious as you'd get a 'could not resolve' error. The fix was to replace dagger implementation dependencies with api, that makes them available to dependant modules as well.

Solution 2 - Android

I fixed it by changing the order of plugins call!

build.gradle

buildscript {
    ext.android_plugin_version = '2.3.3'
    ext.kotlin_version = '1.1.3-2'

        mavenCentral()

        maven { url "https://maven.google.com" }
        maven { url 'https://maven.fabric.io/public' }
        maven { url "https://jitpack.io" }
    }

    dependencies {
        classpath "com.android.tools.build:gradle:$android_plugin_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        classpath 'io.fabric.tools:gradle:1.+'
    }
}

Solution 3 - Android

Before trying anything else, try: Android Studio -> File -> Invalidate cache/restart

This worked for me.

Solution 4 - Android

For me the problem was child module not using AndroidX Activity. I guess the class names clashed.

Added this to resolve:

implementation 'androidx.legacy:legacy-support-v4:1.0.0'

Solution 5 - Android

I solved my problem by deleting files related with dagger hilt from java(generated) and rebuild my project

Solution 6 - Android

Make sure to add same dependencies in the project level as well which are added to the module

Solution 7 - Android

On my case I had to add the required dependency on my main module and compile the last version with:

android {
    configurations.all {
        resolutionStrategy.force "com.squareup.picasso:picasso:${picassoVersion}"
    }
}

Solution 8 - Android

I was getting error for below lib in app level build.gradle

  implementation 'com.google.firebase:firebase-iid:20.0.2'

So the solution is the order in project level build.gradle, So before solving error the structure was

buildscript {
ext.kotlin_version = '1.3.50'
repositories {
   
    google()
    jcenter()
    mavenCentral()
    maven {
        url "https://maven.google.com"
    }

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.5.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.3'
    classpath 'com.google.gms:google-services:4.3.3'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {

    google()
    jcenter()
    mavenCentral()
    maven {
        url "https://maven.google.com" // Google's Maven repository
    }

}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

After Solving the error the struture is :

buildscript {
ext.kotlin_version = '1.3.50'
repositories {
     maven {
        url "https://maven.google.com"
    }
    google()
    jcenter()
    mavenCentral()
  

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.5.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.3'
    classpath 'com.google.gms:google-services:4.3.3'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {
    maven {
        url "https://maven.google.com" // Google's Maven repository
    }
    google()
    jcenter()
    mavenCentral()
   

}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

By default it tries to download using google() as it comes first in the sequence but when we move maven on top of all then it creates the build again using maven and the build succeeds. Cheers :)

Solution 9 - Android

When setting up the crashlytics to my app, I used "recommended" dependency as well, as shown below. But this was the part causes error.

// Firebase Crashlytics
// (Recommended) Add the Google Analytics dependency.
implementation 'com.google.firebase:firebase-analytics:17.2.1'
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

Removing "analytics" line solved my problem.

// Firebase Crashlytics
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

Hope this helps someone else too,

best

Solution 10 - Android

(App)-----depends----(library)

In my case I did not change any dependencies configuration nor i change the order. I had to copy a local pojo(model) jar file from the library module to App.

App is in kotlin library is in java

Its a bug, I should not have pojo.jar in app and library

Solution 11 - Android

I fixed this error upgrading others libraries. My error showed when I added firebase=ads (from google adsmob). So I found a conflict in my firebase-auth (16.0.5) and firebase ads (19.0.1).

Migrating firebase to 19.3.0 solved the problem.

Solution 12 - Android

In my case, I had removed an unused OnFragmentInteractionListener in a fragment:

public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    void onFragmentInteraction(Uri uri);
}

However, In my activity I had failed to remove a reference to this OnFragmentInteractionListener :

public class MainActivity extends AppCompatActivity implements
        MyFragment.OnFragmentInteractionListener {

Strangely, instead of giving an error that indicated the OnFragmentInteractionListener was not found, I received the above "supertypes of the following classes cannot be resolved" with no reference to the classes.

Solution 13 - Android

In my case, I went to the project structure and updated all firebase dependencies to the latest and the highest. At the moment here are implementations with their versions:

    implementation 'com.google.firebase:firebase-auth:19.3.1'
    implementation 'com.google.firebase:firebase-database:19.3.1'
    implementation 'com.google.firebase:firebase-storage:19.1.1'
    implementation 'com.google.firebase:firebase-analytics:17.4.3'

Solution 14 - Android

Well in my case this error randomly occurs which usually occurs during execution through Android Studio.

The root cause was that My Activity class were extending some interfaces which was in another nested package:

package tv.activities

public class MainActivity implements MyListener {

}

package tv.activities.error

interface MyListener {

}

Hence it usually happens during execution but after second run it resolves automatically so no one bother to resolve it. Sometimes Android Studio fail to recognise that interface is accessible so there is no sense of showing error for the same:

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class tv.activities.MainActivity, unresolved supertypes: MyListener

Final Solution:

Making interface public resolves this issue permanently.

public interface MyListener {
}

Or refactor the package accessibility where AS doesn't get confuse

Solution 15 - Android

Update your google play gradle version to the latest
